In one embodiment of the invention, a physical keyboard is operatively connected and/or attached to a removable portable device frame of the removable portable device cover, wherein the removable portable device frame is designed to fit a portable electronic device. In some embodiments of the invention, the operative connection and/or attachment of a physical keyboard to a removable portable frame may be accomplished by using straps, connector ports, and/or wireless protocols. Furthermore, a physical keyboard operatively connected and/or attached to the removable portable device frame may be a foldable physical keyboard which enables easy touch-typing for a user if the foldable physical keyboard is fully expanded.
Description
The present invention generally relates to a portable electronic device. More specifically, the present invention relates to an apparatus and a method for data entry from a removable portable device cover which may at least partially cover, encapsulate, and/or surround a separate portable electronic device.
Numerous portable electronic devices such as cellular phones, portable multimedia players, and navigation systems increasingly utilize touch-screen virtual keyboards for text and other data entry. For example, some popular “smart-phone” devices predominantly reply on relatively large touch-screen surfaces which are configured to show virtual keyboards or virtual keypads for data entry. These smart-phone devices sometimes entirely omit physical keyboards or physical keypads. Similarly, many portable GPS navigation systems and multimedia (e.g. music, video, etc.) players also do not have physical keyboards or physical keypads and rely on touch-screen-based virtual keyboards or virtual keypads instead.
Although the use of virtual keyboards or virtual keypads in these portable electronic devices may exhibit some advantages, such as lower cost of device production and clean-look design factor, some users still strongly prefer using a physical keyboard or a physical keypad which are typically made of plastic and/or rubber materials. It may not be economically advantageous for portable electronic device manufacturers to provide a physical keyboard or a physical keypad as part of a standard factory-spec feature for portable electronic devices that are designed to use a touch-screen virtual keyboard or a virtual keypad in the first place, because the integration costs and the margin pressures may increase significantly merely to provide a redundant method of data entry. Furthermore, even in portable electronic devices which integrate physical keyboards on their surfaces, there may be some dimensional limitations to make keyboards large enough to provide sufficient typing convenience to users.
Therefore, a physical keyboard or a physical keypad can become a popular aftermarket and/or optional accessory item to a portable electronic device, especially among users who prefer physical keyboards or physical keypads over touch-screen virtual counterparts. In addition, even in a portable device which incorporates a physical keyboard or a physical keypad on one of its surfaces, a more comfortable and ergonomic keyboard which can be conveniently carried with the portable device may be highly desirable. Therefore, a novel apparatus and a method for data entry from an accessory item to a portable electronic device may be highly beneficial to users.
Summary and Abstract summarize some aspects of the present invention. Simplifications or omissions may have been made to avoid obscuring the purpose of the Summary or the Abstract. These simplifications or omissions are not intended to limit the scope of the present invention.

For the purpose of describing the invention, a term “readout display” is defined as a display unit on a removable portable device cover which is capable of portraying at least some texts and/or graphics related to a user's data entry.
Furthermore, for the purpose of describing the invention, a term “removable portable device cover” is defined as a separate (i.e. typically aftermarket) skin covering of an outer shell of a portable electronic device. In a preferred embodiment of the invention, a removable portable device cover can surround and/or encapsulate a large portion of a portable electronic device. In another embodiment of the invention, a removable portable device cover can surround and/or encapsulate only a small portion of a portable electronic device. A removable portable device cover can be easily detached or attached to an outer shell of a portable electronic device. Furthermore, in a preferred embodiment of the invention, a removable portable device cover may be custom-fit and/or custom-made for a particular dimension for a particular portable electronic device. In another embodiment of the invention, a general-purpose or a standard-size removable portable device cover may fit a multiple number of portable electronic devices.
Moreover, for the purpose of describing the invention, a term “detachable strap” is defined as a strap which can be repeatedly attached and detached to another surface. In a preferred embodiment of the invention, a detachable strap may be a female Velcro strip or a male Velcro strip configured to be attached to and detached from another Velcro strip.
In addition, for the purpose of describing the invention, a term “physical keyboard” is defined as a keyboard and/or a keypad which has one or more tangible keys which can be touched and/or pressed to enter certain information (e.g. textual, symbolic, graphical) into an electronic device. Furthermore, the term “physical keyboard” can also imply a keyboard and/or a keypad configuration with a joystick, a pointer-stick, a track-ball, an embedded mouse, and/or any other user input devices which may be used in combination with the one or more tangible keys. One example of a physical keyboard according to the term definition herein has one or more hardware switches corresponding to plastic-cap keys above for text and other data entry by a user. This type of a physical keyboard is commonly found in desktop/laptop keyboards and some other electronic devices for data entry. Another example of a physical keyboard according to the term definition herein is a flat-surface keyboard (e.g. a keyboard drawn on a thin piece of plastic, glass, paper, and/or other materials) which has predefined physical areas for typing characters and other symbols. The flat-surface keyboard may be touch-sensitive and/or pressure-sensitive.
Furthermore, in one embodiment of the invention, the first one or more detachable straps (113) can be attached or detached to second one or more detachable straps (115), if the physical keyboard (117) and/or the text/graphic readout display unit (105) are “swung back” to a “strapped-on” position as shown in FIG. 3 . In a preferred embodiment of the invention, the first one or more detachable straps (113) and the second one or more detachable straps (115) are Velcro strips of opposite gender to accommodate repetitive attachment and detachment of both detachable straps (113, 115). In addition, in one embodiment of the invention, the physical keyboard (117) and/or the text/graphic readout display unit (105) can be separately powered by a battery or another power source independent of a portable electronic device which is designed to fit into the removable portable device cover (100). In another embodiment of the invention, the physical keyboard (117) and/or the text/graphic readout display unit (105) may be powered by the portable electronic device through an electrical connection.
In a “fold-out” position as shown in FIG. 1 , a user can type on the physical keyboard (117) and check at least some textual and/or graphical information relevant to his/her data entry on the text/graphics readout display unit (105), regardless of a current state or a current position of a device display on a portable electronic device. In the “fold-out” position, the user may also utilize a main device display on a front surface of a portable electronic device as well as the text/graphics readout display unit (105) on the removable portable device cover (100) for a dual-display use. A user may find typing in the “fold-out” position particularly convenient if a task requires watching the main device display on the front surface of a portable electronic device as he/she types on the physical keyboard (117) attached to a removable portable device cover (100). In the “fold-out”position, the user may get an additional benefit of checking for any typos on a separate text/graphic readout display (105) attached to the removable portable device cover (100) even as he/she also watches the main device display of the portable electronic device.
Moreover, the physical keyboard (117) and/or the text/graphic readout display unit (105) are configured to share (i.e. transmit and/or receive) at least some textual information with the portable electronic device designed to fit into the removable portable device cover (100). In a preferred embodiment of the invention, textual information can be shared among the physical keyboard (117), the text/graphic readout display unit (105), and the portable electronic device using electrical wire connections. In another embodiment of the invention, the textual information can be shared among the physical keyboard (117), the text/graphic readout display unit (105), and the portable electronic device using purely wireless protocols such as Bluetooth. Yet in another embodiment of the invention, the textual information can be shared among the physical keyboard (117), the text/graphic readout display unit (105), and the portable electronic device by using a combination of wired and wireless methods well known in the art.
Continuing with FIG. 1 , in one embodiment of the invention, the removable portable device cover (100) has a removable cover frame (101) which accommodates a rear wall (109), a rear wall band (111), and a plurality of auxiliary connection openings such as a camera lens hole (121), a first cover opening for external connection (123), and a second cover opening for external connection (125). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover. Furthermore, an optional extension of the rear wall (103) or an optional open rear space (103) may be placed above the rear wall band (111) in some embodiments of the invention. Although the rear wall (109), the rear wall band (111), and the plurality of auxiliary connection openings may be desired in some embodiments, incorporations of these particular elements are merely optional for the present invention. In certain cases, the rear wall (109) may be utilized to provide a structural rigidity to the physical keyboard (117) in a “strapped-on” position as shown in FIG. 3 .
Furthermore, in one embodiment of the invention, the first one or more detachable straps (215) can be attached or detached to second one or more detachable straps (213), if the rear panel of the physical keyboard (217) and/or the rear panel of the text/graphic readout display unit (205) are “swung back” to a “strapped-on” position as shown in FIG. 3 . In a preferred embodiment of the invention, the first one or more detachable straps (215) and the second one or more detachable straps (213) are Velcro strips of opposite gender to accommodate repetitive attachment and detachment of both detachable straps (215, 213). In addition, in one embodiment of the invention, the physical keyboard (e.g. 117) and/or the text/graphic readout display unit (e.g. 105) can be separately powered by a battery or another power source independent of a portable electronic device which is designed to fit into the removable portable device cover (200). In another embodiment of the invention, the physical keyboard (e.g. 117) and/or the text/graphic readout display unit (e.g. 105) may be powered by the portable electronic device through an electrical connection.
Moreover, the physical keyboard (e.g. 117) and/or the text/graphic readout display unit (e.g. 105) are configured to share (i.e. transmit and/or receive) at least some textual information with the portable electronic device designed to fit into the removable portable device cover (200). In a preferred embodiment of the invention, textual information can be shared among the physical keyboard (e.g. 117), the text/graphic readout display unit (e.g. 105), and the portable electronic device using electrical wire connections. In another embodiment of the invention, the textual information can be shared among the physical keyboard (e.g. 117), the text/graphic readout display unit (e.g. 105), and the portable electronic device using purely wireless protocols such as Bluetooth. Yet in another embodiment of the invention, the textual information can be shared among the physical keyboard (e.g. 117), the text/graphic readout display unit (e.g. 105), and the portable electronic device by using a combination of wired and wireless methods well known in the art.
Continuing with FIG. 2 , in one embodiment of the invention, the removable portable device cover (200) has a removable cover frame (201) which accommodates a rear wall (209), a rear wall band (211), and a plurality of auxiliary connection openings such as a camera lens hole (221), a first cover opening for external connection (223), and a second cover opening for external connection (225). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover. Furthermore, an optional extension of the rear wall (203) or an optional open rear space (203) may be placed above the rear wall band (211) in some embodiments of the invention. Although the rear wall (209), the rear wall band (211), and the plurality of auxiliary connection openings may be desired in some embodiments, incorporations of these particular elements are merely optional for the present invention. In certain cases, the rear wall (209) may be utilized to provide a structural rigidity to the rear panel of the physical keyboard (217) in a “strapped-on” position as shown in FIG. 3 .
In the “strapped-on” position as shown in FIG. 3 , a user can type on the physical keyboard (317) and check at least some textual and/or graphical information relevant to his/her data entry on the text/graphics readout display unit (305), regardless of a current state or a current position of a device display on a portable electronic device. A user may find typing in the “strapped-on” position particularly convenient if a significant amount of typing is desired on a physical keyboard. Furthermore, the user also may find typing in the “strapped-on” position more convenient because of a larger-size keyboard on a rear surface of an aftermarket device cover as a substitute for a typically-cramped keyboard on a front surface of a portable device itself. It should be noted that the size of a keyboard on a removable portable electronic device cover embodied by the present invention can be even larger if a “landscape” orientation is utilized, as shown in FIGS. 8˜9 .
Continuing with FIG. 3 , the physical keyboard (317) and/or the text/graphic readout display unit (305) are configured to share (i.e. transmit and/or receive) at least some textual information with the portable electronic device designed to fit into the removable portable device cover (300). In a preferred embodiment of the invention, textual information can be shared among the physical keyboard (317), the text/graphic readout display unit (305), and the portable electronic device using electrical wire connections. In another embodiment of the invention, the textual information can be shared among the physical keyboard (317), the text/graphic readout display unit (305), and the portable electronic device using purely wireless protocols such as Bluetooth. Yet in another embodiment of the invention, the textual information can be shared among the physical keyboard (317), the text/graphic readout display unit (305), and the portable electronic device by using a combination of wired and wireless methods well known in the art.
Continuing with FIG. 3 , in one embodiment of the invention, the removable portable device cover (300) has a removable cover frame (301) which accommodates a rear wall (309), a rear wall band (311), a first cover opening for external connection (321), and a second cover opening for external connection (315). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover. Furthermore, an optional extension (303) of the rear wall or an optional open rear space (303) may be placed above the rear wall band (311) in some embodiments of the invention. Although the rear wall (309), the rear wall band (311), and a plurality of auxiliary connection openings (e.g. 315, 321) may be desired in some embodiments, incorporations of these particular elements are merely optional for the present invention. In certain cases, the rear wall (309) may be utilized to provide a structural rigidity to the rear panel of the physical keyboard (317) in a “strapped-on” position as shown in FIG. 3 .
Furthermore, in an embodiment of the invention as shown in FIG. 4 , a plurality of auxiliary connection openings such as a first cover opening for external connection (405), a second cover opening for external connection (411), and a camera lens hole (403) can be incorporated on a surface of a removable cover frame (401). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover.
In one example of an embodiment as shown by FIG. 5 , the keyboard/display connector port (513) enables a physical docking and a separation of a physical keyboard (509) and/or a text/graphic readout display unit (507). When the physical keyboard (509) and/or the text graphic readout display unit (507) are docked to the keyboard/display connector port (513), the removable cover frame (503) and/or a portable electronic device inside the removable cover frame (503) may be able to recharge a battery contained by the physical keyboard (509) and/or the text/graphic readout display unit (507). Furthermore, the physical keyboard (509) and the text/graphic readout display unit (507) docked to the keyboard/display connector port (513) may still enable data entry operations to a user either via a wired or a wireless communication with a portable electronic device at least partially surrounded, encapsulated, and/or covered by the removable cover frame (503), even as the battery contained by the physical keyboard (509) and/or the text/graphic readout display unit (507) is charging. In a preferred embodiment of the invention, the text/graphic readout display unit (507) is capable of displaying at least some visual information to allow a user to see what he/she is typing into the physical keyboard (509).
Moreover, if the physical keyboard (509) and the text/graphic readout display unit (507) are separated from the keyboard/display connector port (513), as shown in FIG. 6 , then a user can still enter text information and other relevant data to the physical keyboard (509), which in turn communicates with the portable electronic device wirelessly. Examples of wireless communication protocols used for sharing text information and other relevant data between the physical keyboard (509) and the portable electronic device include Bluetooth and IEEE 802.11-based Wi-Fi protocols. These wireless communication protocols may also incorporate commonly-known security features such as a wireless encryption protocol (WEP) and a secure authentication to provide data security for at least some information communicated between the physical keyboard (509) and the portable electronic device.
In one example of an embodiment as shown by FIG. 6 , the keyboard/display connector ports (613A, 613B) enable a physical docking and a separation of a physical keyboard (609) and/or a text/graphic readout display unit (607). When the physical keyboard (609) and/or the text graphic readout display unit (607) are docked to the keyboard/display connector port (513), the removable cover frame (603) and/or a portable electronic device inside the removable cover frame (603) may be able to recharge a battery contained by the physical keyboard (609) and/or the text/graphic readout display unit (607). Furthermore, the physical keyboard (609) and the text/graphic readout display unit (607) docked to a removable cover frame side (613A) of the keyboard/display connector ports (613A, 613B) may still enable data entry operations to a user either via a wired or a wireless communication with a portable electronic device at least partially surrounded, encapsulated, and/or covered by the removable cover frame (603), even as the battery contained by the physical keyboard (609) and/or the text/graphic readout display unit (607) is charging. In a preferred embodiment of the invention, the text/graphic readout display unit (607) is capable of displaying at least some visual information to allow a user to see what he/she is typing into the physical keyboard (609).
Moreover, if the physical keyboard (609) and the text/graphic readout display unit (607) are separated from the removable cover frame side (613A) of the keyboard/display connector ports (613A, 613B), as shown in FIG. 6 , then a user can still enter text information and other relevant data to the physical keyboard (609), which in turn communicates with the portable electronic device wirelessly. Examples of wireless communication protocols used for sharing text information and other relevant data between the physical keyboard (609) and the portable electronic device include Bluetooth and IEEE 802.11-based Wi-Fi protocols. These wireless communication protocols may also incorporate commonly-known security features such as a wireless encryption protocol (WEP) and a secure authentication to provide data security for at least some information communicated between the physical keyboard (609) and the portable electronic device.
Furthermore, in one embodiment of the invention, the first one or more detachable straps (801) can be attached or detached to second one or more detachable straps (809), if the physical keyboard (819) and/or the text/graphic readout display unit (803) are “swung back” to a “strapped-on” position as shown in FIG. 9 . In a preferred embodiment of the invention, the first one or more detachable straps (801) and the second one or more detachable straps (809) are Velcro strips of opposite gender to accommodate repetitive attachment and detachment of both detachable straps (801, 809). In addition, in one embodiment of the invention, the physical keyboard (819) and/or the text/graphic readout display unit (803) can be separately powered by a battery or another power source independent of a portable electronic device which is designed to fit into the removable portable device cover (800). In another embodiment of the invention, the physical keyboard (819) and/or the text/graphic readout display unit (803) may be powered by the portable electronic device through an electrical connection.
In a “fold-out” position as shown in FIG. 8 , a user can type on the physical keyboard (819) and check at least some textual and/or graphical information relevant to his/her data entry on the text/graphics readout display unit (803), regardless of a current state or a current position of a device display on a portable electronic device. In the “fold-out” position, the user may also utilize a main device display on a front surface of a portable electronic device as well as the text/graphics readout display unit (803) on the removable portable device cover (800) for a dual-display use. A user may find typing in the “fold-out” position particularly convenient if a task requires watching the main device display on the front surface of a portable electronic device as he/she types on the physical keyboard (819) attached to a removable portable device cover (800). In the “fold-out” position, the user may get an additional benefit of checking for any typos on a separate text/graphic readout display (803) attached to the removable portable device cover (800) even as he/she also watches the main device display of the portable electronic device.
Moreover, the physical keyboard (819) and/or the text/graphic readout display unit (803) are configured to share (i.e. transmit and/or receive) at least some textual information with the portable electronic device designed to fit into the removable portable device cover (800). In a preferred embodiment of the invention, textual information can be shared among the physical keyboard (819), the text/graphic readout display unit (803), and the portable electronic device using electrical wire connections. In another embodiment of the invention, the textual information can be shared among the physical keyboard (819), the text/graphic readout display unit (803), and the portable electronic device using purely wireless protocols such as Bluetooth. Yet in another embodiment of the invention, the textual information can be shared among the physical keyboard (819), the text/graphic readout display unit (803), and the portable electronic device by using a combination of wired and wireless methods well known in the art.
Continuing with FIG. 8 , in one embodiment of the invention, the removable portable device cover (800) has a removable cover frame (821) which accommodates a rear wall (815) and a plurality of auxiliary connection openings such as a camera lens hole (813), a first cover opening for external connection (811), and a second cover opening for external connection (807). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover. Although the rear wall (815) and the plurality of auxiliary connection openings (e.g. 811, 807, 813) may be desired in some embodiments, incorporations of these particular elements are merely optional for the present invention. In certain cases, the rear wall (815) may be utilized to provide a structural rigidity to the physical keyboard (819) in a “strapped-on” position as shown in FIG. 9 .
In the “strapped-on” position as shown in FIG. 9 , a user can type on the physical keyboard (909) and check at least some textual and/or graphical information relevant to his/her data entry on the text/graphics readout display unit (903), regardless of a current state or a current position of a device display on a portable electronic device. A user may find typing in the “strapped-on” position particularly convenient if a significant amount of typing is desired on a physical keyboard. Furthermore, the user also may find typing in the “strapped-on” position more convenient because of a larger-size keyboard on a rear surface of an aftermarket device cover as a substitute for a typically-cramped keyboard on a front surface of a portable device itself. The “landscape” orientation of a physical keyboard (819, 909) in FIGS. 8˜9 is particularly ergonomic to a user who prefers a larger size physical keyboard for convenient typing.
Continuing with FIG. 9 , the physical keyboard (909) and/or the text/graphic readout display unit (903) are configured to share (i.e. transmit and/or receive) at least some textual information with the portable electronic device designed to fit into the removable portable device cover (900). In a preferred embodiment of the invention, textual information can be shared among the physical keyboard (909), the text/graphic readout display unit (903), and the portable electronic device using electrical wire connections. In another embodiment of the invention, the textual information can be shared among the physical keyboard (909), the text/graphic readout display unit (903), and the portable electronic device using purely wireless protocols such as Bluetooth. Yet in another embodiment of the invention, the textual information can be shared among the physical keyboard (909), the text/graphic readout display unit (903), and the portable electronic device by using a combination of wired and wireless methods well known in the art.
Continuing with FIG. 9 , in one embodiment of the invention, the removable portable device cover (900) has a removable cover frame (915) which accommodates a rear wall (e.g. 815), a first cover opening for external connection (911), and a second cover opening for external connection (901). Examples of external connections through cover openings include data and/or power outlet connections for a portable device designed to be placed inside the removable portable device cover. Although the rear wall (e.g. 815) and a plurality of auxiliary connection openings (e.g. 911, 901) may be desired in some embodiments, incorporations of these particular elements are merely optional for the present invention. In certain cases, the rear wall (e.g. 815) may be utilized to provide a structural rigidity to the rear panel of the physical keyboard (909) in a “strapped-on” position as shown in FIG. 9 .
In the preferred embodiment of the invention, the first piece (1003) contains a left-half of a “QWERTY” keyboard and the second piece (1007) contains a right-half of the “QWERTY” keyboard. Furthermore, the foldable physical keyboard (1003, 1007) is capable of transferring or receiving user input data and other relevant data with a portable electronic device (1009) which fits into the removable cover frame (1001). One advantage of the foldable physical keyboard configuration as shown in FIG. 10 is an extensive size of the foldable physical keyboard in a fully-expanded position, which allows an easy touch-typing by a user. Another advantage of this foldable physical keyboard configuration is that the foldable physical keyboard (1003, 1007) can be neatly folded into a one-piece cover (e.g. 1203, 1207 of FIG. 12 ) as part of an aftermarket removable portable device cover (1000 of FIG. 10 , 1100 of FIG. 11 , 1200 of FIG. 12 ) for a portable electronic device (e.g. 1009), thereby allowing a user to conveniently carry an expandable keyboard for portable touch-typing with any portable electronic device (e.g. 1009) which fits into the removable cover frame (1001).
Furthermore, the foldable physical keyboard configuration as shown in FIG. 10 allow a display screen of the portable electronic device (e.g. 1009) to function as a convenient type readout screen in a “landscape” aspect ratio as a user is touch-typing into the foldable physical keyboard. However, the foldable physical keyboard configuration for a removable portable device cover (100) is not limited to an L-shape as shown in FIG. 10 and may include a variety of different folding shapes. For example, in one embodiment of the invention, a folding physical keyboard configuration may attach a removable cover frame (e.g. 1001) on a left side or a right side of the foldable keyboard (1003, 1007) to form a line-shape configuration, instead of on top of the first piece (1003) as illustrated in FIG. 10 as a preferred embodiment.
In an embodiment of the invention as shown in FIG. 11 , the removable cover frame (1101), which is at least partially covering, surrounding, and/or encapsulating a portable electronic device inside, is folded on top of the first piece (1103). Then, as shown in FIG. 12 , the second piece (1107) can be folded on top of a rear surface of the removable cover frame (1101). Once both the first piece (1103) and the second piece (1107) of keyboard elements are folded, the folded keyboard (1103, 1107) can function as an exterior aftermarket top and bottom covers for a removable cover frame (1101) which is configured to fit a portable electronic device. In another embodiment of the invention, a foldable keyboard can comprise multiple pieces beyond the two-piece configuration shown in FIG. 10 and FIG. 11 . Yet in another embodiment of the invention, a foldable keyboard can fold itself first before getting folded to a top surface or a bottom surface of a removable cover frame. The folded physical keyboard (1103, 1107) as part of the removable portable device cover (1100) allows a user to conveniently carry an expandable keyboard for portable touch-typing with any portable electronic device which fits into the removable cover frame (1101).
In an embodiment of the invention as shown in FIG. 12 , the removable cover frame (1201), which is at least partially covering, surrounding, and/or encapsulating a portable electronic device inside, is folded on top of the first piece (1203). Then, as shown in FIG. 12 , the second piece (1207) can be folded on top of a rear surface of the removable cover frame (1201). Once both the first piece (1203) and the second piece (1207) of keyboard elements are folded, the folded keyboard (1203, 1207) can function as an exterior aftermarket top and bottom covers for a removable cover frame (1201) which is configured to fit a portable electronic device. In another embodiment of the invention, a foldable keyboard can comprise multiple pieces beyond the two-piece configuration shown in FIG. 10˜12 . Yet in another embodiment of the invention, a foldable keyboard can fold itself first before getting folded to a top surface or a bottom surface of a removable cover frame. The folded physical keyboard (1203, 1207) as part of the removable portable device cover (1200) allows a user to conveniently carry an expandable keyboard for portable touch-typing with any portable electronic device which fits into the removable cover frame (1201).
One or more apparatuses and methods for data entry from a removable portable device cover have been disclosed. The present invention exhibits several advantages over conventional apparatuses and methods of data entry into a portable electronic device. First, by integrating a physical keyboard interface as part of a removable portable device cover, the present invention provides a large-surface keyboard for touch-typing which can be conveniently carried with a portable electronic device whenever a user is covering a portable electronic device with an embodiment of the present invention. Second, by incorporating a strap-on and fold-out design (FIGS. 1˜3 , FIGS. 8˜9 ), an embedded rear surface design (FIG. 4 ), a wireless port design (FIG. 5˜6 ), and a foldable-keyboard design (FIGS. 10˜12 ) as various embodiments of the invention, the present invention discloses a variety of convenient and portable extra keyboard interfaces which can be carried as removable portable device covers.
While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein.
